Chad Michael Murray, Sophia Bush, Paris Hilton
When: September 2005
Like so many other actresses, Sophia Bush, whose beauty often goes underrated, fell in love while on set. After meeting on the CW's One Tree Hill, Sophia married co-star Chad Michael Murray after two years of dating. The couple seemed to be a match made in heaven, that is, until Chad met billionaire heiress and night vision queen Paris Hilton. The two appeared together in 2005's House of Wax, and rumors of infidelity on the part of Murray began to swirl.
Before long, after just five months, the marriage was annulled. Bush later said, "It devastates me now that I have been reduced to a Hollywood statistic, another joke marriage. I never expected to be married more than once...because I knew what I was getting into and will always believe in love."
